"bunch of logs to read" = PowerShell + "select-string" From: Silvio L.

Have a bunch of logs to read after this holiday. One problem we have with them is that they sell things ( iron, steel, the like ) . So , when their customers can´t send them email for consulting prices, they don´t sell and blame us. And if we say ( or even prove ) that the problem is on their customers´s end, they still wants us to solve it on this end.. ----- Original Message ----- From: Richard Stovall To: MS-Exchange Admin Issues Sent: Monday, February 15, 2010 4:47 PM Subject: Re: Disappearing e-mail messages.... Good to know. Thanks for following up with that. I would think that the OP should have plenty to work with now.

Understood. The question I posed was whether there is anything useful in the SMTP logs if the OP's Exchange server is doing RBL rejections. Perhaps my wording was as clear as mud. A little Google searching leads me to believe that connection filtering-related data is logged in the SMTP log on Exchange 2003, but I don't know for sure because in my setup I can't test it. Even if it is, however, I wonder if there is anything useful beyond the sending IP address. If it is rejected because of a positive RBL hit, does the SMTP conversation ever get as far as the "Mail from:" or anything else that would help identify the rejected sender by email address? I kinda doubt it, and the OP might not know the sending sender's IP. 'Course all of this is moot if he doesn't have RBLs configured...

I agree and was thinking the same thing. What happens, however, if the connection is dropped b/c of sender's listing in an RBL? Would there be anything in the SMTP logs in that case? All my RBLs are configured on edge devices so I don't have a way to know what would happen if they were configured directly on Exchange.

If you don't have anything in this server logs then that means that messages don't reach to your server and problem is elsewhere. And it's useless to search something from spam folders and other places when message haven't even reached to your server. If that is the case then you must start pester your customers ISP's or IT staff(if they have any) for more information about problem. Markko -----Original Message----- From: Silvio L.

Hello, Could someone suggest where can I look for the reasons for some disappearing messages ? Customers that were able to send email to our people are saying they sent the emails, but our people say they never received. This started some time ago. Nothing in logs, nothing in spam filters. I will disable all filtering to see if it impacts , but don´t think so. Have perused through the 1k messages / day of spam, but the "phantom" messages are not here. Now , I know that users cannot be trusted not to delete a Mailer Daemon message without reading, but this is happening with people who used to communicate via email normally since a long time ago. Any suggestion for searching the problem ? System is 2003 - R2 with Exchange 2003.
